Licence for Alterations: What Business Tenants Need Before Making Changes

If you lease a shop, office, warehouse, studio or hospitality site in New Zealand, you usually cannot just start building, painting, cutting walls or installing signage because it suits your fit-out plan. Business tenants often get caught by three avoidable mistakes: assuming the lease already allows the works, spending money on contractors before landlord consent is documented, and agreeing to broad make-good obligations without understanding the cost at the end of the lease.

A licence for alterations is the document that usually fills that gap. It records the landlord's consent to specific changes and sets the rules for how the work must be done. That matters whether you are refreshing a retail tenancy, fitting out a clinic, adding mezzanine storage, installing cabling, upgrading ventilation or changing signage.

This guide explains what a licence for alterations means in New Zealand, when commercial tenants usually need one, what to check before you sign, and where business owners commonly take on unnecessary risk.

Overview

A licence for alterations is a written landlord consent that lets a commercial tenant carry out defined works to leased premises, subject to conditions. It sits alongside your lease, not instead of it, and it should match the actual building works, approvals, timeframes and end-of-lease obligations involved.

• Check whether your lease already restricts alterations, fit-out works, signage, services installations or structural changes.
• Make sure the licence clearly describes the approved works, plans, specifications and contractor requirements.
• Confirm who pays for consents, professional reports, reinstatement, insurance and damage repair.
• Review whether the landlord can require make-good at the end of the term, and exactly what that means in practice.
• Check whether body corporate rules, local council approvals, health and safety duties or building consent issues also apply.
• Do not start work until the consent document is signed and any conditions are satisfied.

What Licence for Alterations Means For New Zealand Businesses

A licence for alterations is usually the landlord's formal permission for a tenant to change leased premises in a particular way. For New Zealand businesses, it is most relevant in commercial leasing, especially where a commercial lease says the tenant must not alter, add to or interfere with the premises without prior written consent.

In plain English, the document answers a practical problem. You want to make changes so the space works for your business, but the landlord wants control over what happens to its property. A licence for alterations sets out the compromise.

When businesses usually need one

You may need a licence for alterations before you sign a building contract or before you spend money on setup if your proposed works go beyond minor removable items. Common examples include:

• installing partition walls, counters or built-in shelving
• changing flooring, ceilings or lighting systems
• adding plumbing, drainage, extraction or ventilation
• upgrading data cabling, alarms, security systems or air conditioning
• putting up external signage or changing the shopfront
• creating treatment rooms, kitchen areas or storage areas
• making structural or semi-structural changes

Even works that feel routine from an operations point of view can still trigger a lease consent requirement. A café fit-out, a clinic refit, a beauty studio conversion or warehouse racking project can all raise landlord approval issues.

How it fits with the lease

The lease remains the main contract for occupation of the premises. The licence for alterations is a separate document that deals with a specific set of approved works.

That distinction matters because the licence should not quietly change other key lease rights unless that is intentional. For example, a clause about reinstatement, landlord access or insurance obligations could create extra obligations that go beyond what the lease originally said. This is where founders often get caught.

Why New Zealand tenants should treat it seriously

The main risk is not just whether you can do the works. The bigger issue is often who carries the cost and responsibility if something goes wrong or if the landlord later demands the space be returned to its previous condition.

For New Zealand SMEs, a poorly drafted licence for alterations can create problems such as:

• delays to opening or trading because approvals were incomplete
• unexpected legal or consultant costs payable to the landlord
• disputes over whether the finished works matched the approved plans
• arguments about damage to neighbouring premises or common areas
• large make-good bills at lease end

Commercial property arrangements also often involve other documents and parties. If the premises are part of a unit title development, body corporate requirements may matter. If the building is older or complex, engineers, fire consultants or building managers may need to sign off. If the tenant has borrowed against the business or taken on investor commitments, project delays can have wider commercial consequences.

It is not only about major construction

Many tenants assume a licence for alterations is only needed for knocking down walls. That is too narrow. Landlords often require formal consent for any work that affects the building fabric, essential services, appearance, compliance status or future lettability of the space.

If the works connect to plumbing, mechanical ventilation, fire systems, disability access, grease traps, extraction, signage or power capacity, expect much closer review. The same is true if your industry has site-specific legal requirements, such as food premises, health services, childcare or manufacturing uses.

Legal Issues To Check Before You Sign

Before you sign a licence for alterations, make sure the document matches the actual project and fairly allocates risk. The details matter more than the label.

Scope of works and approved plans

The licence should precisely identify what the landlord is consenting to. Vague wording causes disputes later, especially if the fit-out evolves during design or procurement.

The document should usually include:

• drawings and plans
• specifications or a written scope
• materials and finishes, where relevant
• details of services work, such as plumbing, electrical or HVAC
• any staging or timing requirements

If the plans change after signing, you may need updated consent. Do not assume an email approval from a property manager will be enough if the formal licence says variations need written agreement.

Consistency with the lease

Your lease may already set out rules on alterations, signage, landlord costs, reinstatement and access. The licence should be checked against those clauses line by line.

Look closely at whether the new document adds obligations such as:

• paying the landlord's legal fees, surveyor fees or consultant costs without a cap
• automatic reinstatement at the end of the term, even for improvements the landlord benefits from
• broad indemnities or liability clauses for loss that extend beyond your actual works
• extra insurance requirements not reflected in the lease
• new rights for the landlord to enter and stop works

None of those points are necessarily unreasonable, but they should be understood and negotiated before work begins.

Building consent and other approvals

Landlord consent does not replace regulatory approvals. Depending on the works, you may also need building consent, council approvals, engineering input, fire compliance review or specialist sign-off.

Responsibility for obtaining those approvals should be clearly allocated. The licence should state who must apply, who pays, and whether work can start only after copies are provided to the landlord.

If your business operates in a regulated environment, the fit-out may affect your ability to trade from the premises. Think about issues such as:

• food premises layout and extraction requirements
• clinical or treatment room design
• accessibility expectations for customers and visitors
• fire egress and occupancy compliance
• storage or use of specialised equipment

A fit-out that looks fine from a design point of view may still create compliance problems for the business.

Contractors, health and safety, and site rules

The tenant usually remains responsible for its contractors and subcontractors. The licence often requires qualified trades, evidence of insurance, compliance with building rules and adherence to health and safety procedures.

That matters because commercial sites are often active workplaces. If work affects other tenants, common areas, deliveries or building systems, the landlord will want tight controls. Before you sign, check whether the licence requires:

• specific working hours
• induction or access procedures
• lift booking and loading restrictions
• noise, dust or waste management conditions
• protection for common areas and neighbouring premises

You should also make sure your contractor agreements line up with the obligations you are accepting under the licence. If the landlord requires a particular standard or timing, your builder contract should reflect that.

Damage, insurance and liability

Most licences for alterations place the risk of damage from the works on the tenant. That is expected, but the wording should be proportionate.

Check who is responsible if the works:

• damage the base building
• interrupt services to other occupiers
• trigger insurance issues
• cause delay to other tenants or the landlord's project works
• reveal pre-existing defects in the building

Pre-existing condition is a common flashpoint. A schedule of condition, photographs or a clear starting record can help avoid arguments about whether your contractor caused an issue that was already there.

Ownership of the improvements

Not every tenant improvement remains the tenant's property. Some fixtures and fit-out items may become part of the building once installed.

The licence should deal with ownership and removal rights. This matters at lease end, on assignment, or if your business is sold. If expensive fit-out is involved, you do not want uncertainty over whether you can remove it, must leave it, or must pay to remove it.

Make-good and reinstatement

This is often the most expensive clause in the whole exercise. A licence for alterations commonly says the landlord can require the tenant to reinstate the premises at the end of the lease.

That sounds simple, but the real questions are:

• does the landlord have an absolute right to require removal
• must notice be given by a certain date
• does reinstatement include hidden services and penetrations
• who decides the standard of finish
• what happens if the landlord wants to keep part of the fit-out

Where possible, tenants often try to narrow this clause. For example, the landlord might agree now that certain works can remain at lease end. Getting that clarity in writing can save a major dispute later.

Timing, delays and default

The licence should say when the works must start and finish, and what happens if they are delayed. If your lease commencement, rent-free period or opening date depends on the fit-out, timing clauses matter commercially as well as legally.

Watch for default provisions that let the landlord revoke consent, enter the premises or complete remedial works at your cost. Those rights may be fair where there is real breach, but the triggers should be clear and not overly broad.

Common Mistakes With Licence for Alterations

The most common mistake is treating landlord consent as an admin step after commercial decisions have already been locked in. Once you have ordered bespoke joinery, signed with contractors or promised an opening date, your negotiating leverage drops fast.

Starting work on the strength of informal approval

A verbal go-ahead, a text message or a friendly email from the property manager is not a substitute for signed written consent where the lease requires it. If the relationship later sours, you may be left arguing about authority and scope.

This often happens when a founder is under pressure to open quickly. The business starts demolition or fit-out based on a casual nod, then discovers the landlord's lawyer expects a formal licence with extra conditions and costs.

Assuming non-structural means low risk

Tenants often think, if it is not structural, it should be fine. But plenty of non-structural changes can still affect building services, compliance, access, fire safety or the appearance of the premises.

Built-in shelving, external signage, extraction systems, plumbing relocations and partition walls can all create lease and approval issues. Low cost does not mean low legal significance.

Ignoring the landlord's costs clause

Many licences require the tenant to pay the landlord's reasonable legal and consultant costs for reviewing the request and documenting consent. Businesses sometimes notice this only after the invoice arrives.

Before you sign, check whether those costs are capped, whether they are payable even if the project does not proceed, and whether external consultant costs are really necessary for the type of work proposed.

Accepting broad make-good language

Founders tend to focus on opening costs, not exit costs. That is understandable, but a broad reinstatement clause can create a large future liability, especially after a long lease where records are poor and staff have changed.

A better approach is to identify at the start which items must be removed, which may remain, and what standard will apply if make-good is required.

Forgetting about body corporate or building manager rules

In office towers, retail centres and unit title developments, landlord consent may only be one piece of the puzzle. Building managers and body corporates often have separate rules about access, contractors, noisy works, penetrations, signage and insurance certificates.

If you discover those rules after signing construction contracts, delays and extra cost are likely.

Letting the build contract drift away from the licence terms

Your licence may require licensed trades, certain insurances, specific completion standards and repair obligations. If your contractor agreement does not mirror those requirements, the business may wear the gap.

For example, if the landlord requires immediate repair of common area damage but your builder contract is vague on responsibility and timing, the tenant may have to fix the issue first and recover later, if at all.

Not keeping a paper trail

Alteration projects change as they go. Businesses often approve small design tweaks on site without documenting them properly.

That becomes a problem if the landlord later says the finished works differ from the approved scope. Keep signed plans, variation approvals, consultant sign-offs, producer statements, warranties and photographs together in one file. It will help during the tenancy and at lease end.

FAQs

Do I always need a licence for alterations under a commercial lease?

No. It depends on your lease and the type of works. Some minor removable items may not need formal consent, but many fit-out changes do, especially where they affect services, structure, appearance or compliance.

Can a landlord refuse consent to alterations?

Often yes, depending on the lease wording and the nature of the works. Some leases say consent cannot be unreasonably withheld for certain non-structural alterations, but that is not automatic and the facts matter.

Who pays for the licence for alterations?

The tenant commonly pays its own costs and the landlord's reasonable legal or consultant costs connected with the consent. The document should state this clearly, and it is worth checking whether any cost cap can be agreed.

Does landlord consent cover council or building approvals too?

No. A landlord's licence for alterations is separate from any building consent, council requirement or specialist approval that may apply to the works. You may need both contractual consent and regulatory approval.

Do I have to remove the fit-out when the lease ends?

Maybe. That depends on the lease and the licence terms. Some licences let the landlord require reinstatement, while others allow certain approved works to remain. The safest approach is to get the position written clearly at the start.
